Title: Feed device, particularly for the cross-slides of grinding machines
IPC: B24B47/20
Filed: 1928-02-09
Abstract: 286,596. Jung, K. March 5, 1927, [Convention date]. Driving machines.-A feed mechanism particularly suitable for feeding the cross-slides of grinding-machines is operated independently of the movements of the longitudinal slide of the machine by hydraulic means controlled by a handactuated throttle valve to vary the rate of feed. The table or longitudinal slide 1 carries a crossslide 6 provided with a driving-shaft 7 connected by belt gearing 9 either to the grinding wheel or to the work, preferably the former. The shaft 7 also drives through worm gearing 10, 11, a shaft 13 operating two oil-pumps 14, 15. The delivery from the pump 14 passes through a throttlevalve 17 and pipe 16 to a valve 18' mounted on a spindle 18 carrying a connecting rod which operates through ratchet mechanism 58, spindle 57 and gearing 61 to rotate an eccentric pin 63 working in a block secured to a normally stationary rack 66. The movements of the pin 63 transmitted from the spindle 18 produce the required cross-feed movement. Hand adjustment of the cross-slide is effected by moving the rack 66 by means of worm gearing 69 and pinion 67. The spindle 18 also carries a rotary piston 39 working in a chamber 38. In the position of the valve 18<1> shown in Fig. 2, delivery from the pump 14 passes through passages 16, 19, 20, 21 to a piston 23 while from the other side of this piston fluid passes through passages 24 - - 26 back to a reservoir. The movement of the piston 23 is transmitted by a lever 47 to a piston-valve 36 working in a cylinder 33 which is supplied from the pump 15 through passages 31, 32. The valve 36 is thus moved to the position, shown in Fig. 4, wherein fluid passes through a passage 37 to one side of the piston 39 and moves this piston to rotate the valve 18' through 90‹. From the other side of the piston 39 fluid returns to the reservoir through passages 44, 42. When the valve 18<1> has been thus rotated, fluid passes from the pump 14 through the passages 16, 25, 26 to the right-hand side of the piston 23 which is thus shifted to the left and acts through a lever 46 to move the valve 36 to its right-hand position and allow fluid to flow from the pump 15 through the passages 32, 41 to the left side of the piston 39. At each oscillation of the spindle 18 the pawl 58 is operated to impart a feed movement. To control the rate of feed the throttle valve 17 may be set by means of a hand lever 30. A spring-ball safetyvalve is also incorporated in the valve 17.

Title: Improvements in and relating to television or the like transmission systems
IPC: H04N5/10
Filed: 1933-02-13
Abstract: 416,720. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Blyth Road, Hayes, Middlesex, MANIFOLD, M. BOWMAN-, Heathcot, Worplesdon Station, and CORK, E. C., 53, Stoneleigh Drive, Worcester Park, both in Surrey. Feb. 13, 1933, No. 4434. [Classes 40 (iii) and 40 (v).] A circuit for separating or mixing synchronizing impulses of two different frequencies in a television system comprises a Wheatstone bridge, the mixed frequencies being applied to or taken from an arm of the bridge while the separate frequencies are taken from or applied to two conjugate diagonals. The bridge is balanced so as to discouple the single-frequency circuits. Fig. 3 shows an arrangement for separating line - frequency synchronizing - impulses from frame-frequency synchronizing- impulses, and for producing oscillations of saw-tooth wave-form. The arms of the bridge are formed by the condensers 5, 6, the resistance 4, and the resistance of a valve 1 in shunt with the anode resistance 2 and battery. The valve 1 may be the second detector of a wireless receiver for dealing with a carrier having a sub-carrier modulated by two sets of synchronizing impulses. The higher-frequency impulses are shunted by the condensers 5, 6 so that they are attenuated at the terminals a, b, and the lower-frequency impulses are derived via these terminals. The higher-frequency impulses, on the other hand, pass through the primary 13 of a transformer and a condenser (not shown) may be inserted in series with this coil for attenuating the frame-frequency impulses. In modifications, the frame-frequency impulses may be kept away from coil 13 by a series condenser, and an anode coupling condenser may be used (8, 3, Fig. 1, not shown) ; the condenser 5 and resistance 4 may respectively be replaced by a resistance and an inductance, which latter may be shunted by a resistance for compensating the internal capacity of the valve (11, 10, 12, Fig. 2 not shown) ; the resistance 4 may be shunted by a condenser to compensate for the capacity of the valve ; and a bridge similar to that shown may be used for mixing the two frequencies before transmission. Producing saw - tooth wave form. Two secondaries 15, 16 are coupled to the grids of valve 18 in such a manner that the two grid circuits react upon one another to produce a rapid opening and closing of the valve in response to synchronizing-impulses. The valve controls the charging and discharging of condenser 21 through resistance 20.

Title: Manufacture of ª .ª -dimethylbenzylhydroperoxide
IPC: C07C409/10
Filed: 1951-03-02
Abstract: a ,a -Dimethylbenzylhydroperoxide is made by reacting isopropylbenzene with molecular oxygen at elevated temperatures not exceeding the boiling temperature of the isopropylbenzene, preferably between 65 DEG  and 115 DEG  C., in the presence of a transition metal the concentration of which dissolved in the reaction mixture does not exceed that concentration of the same catalyst which decomposes 1/20 of the peroxide content of a mixture of 15 parts by weight of a ,a -dimethylbenzylhydroperoxide and 85 parts by weight of isopropylbenzene at 80 DEG  C. within 45 hours.  Transition metals are defined as those which are capable of changing their valency and which are oxidation catalysts for organic compounds those specified being iron, cobalt, nickel, copper, lanthanum, lead, thallium, manganese and cerium, the latter being especially suitable.  The metals are preferably applied as compounds soluble or dispersible in isopropylbenzene, e.g. stearates, palmitates, oleates and naphthenates, the latter being preferred.  Oxides of the metals may be used although soluble only with difficulty in the reaction medium, e.g. PbO, Pb2O3, Pb3O4 and PbO2.  Mixtures of the catalysts may be used.  Tables are provided showing the maximum concentration of metal permissible and the effect on product yield with changes in catalyst concentration, low concentrates favouring high yields.  The catalyst concentration may be increased during the course of the reaction. Diluents, e.g. benzene, may be present.  Advisably the reaction is completed within a short time, the unreacted isopropylbenzene being returned after separation of the hydroperoxide.  Vigorous agitation of the reaction mixture is an advantage.  In examples, isopropylbenzene is treated with oxygen at temperatures ranging from 80 DEG  to 100 DEG  C. in the presence of manganese, cerium, copper, lead, iron or nickel naphthenates, lead oxide, lead dioxide and a mixture of lead oxide and dioxide.
